Abstract

fetched live from OpenAlex

This paper proposes a new technique for peak-to-average power ratio (PAPR) reduction using post-compensation for a RF front-end of OFDM-based transmitters. A clipping function is first applied to the base band input signal in order to optimize the efficiency of the power amplifier (PA). Then a post-compensation technique is used to correct for the clipping in-band and out-of-band noise. The injection of the error signal, computed digitally in base band and transposed to the RF frequency, at the output of the PA allowed the reduction of the error vector magnitude and adjacent channel interference ratio

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
